Abstract
The invention discloses an exhaust silencer for improving an oil separation effect of a compressor. The exhaust silencer comprises a cover body and an installation hole arranged in the cover body, wherein a gas flow channel on the inner wall surface of the cover body is provided with a centrifugal guide channel with a function of adhering oil drops to refrigerant high-pressure gas containing the oil drops through centrifugal guide flow.
Description
[technical field]
The present invention relates to the oil separating device of compressor, relate in particular to a kind of exhaust silencer that improves the compressor oil separating effect.
[background technique]
Existing compressor oil segregating unit all is terminal at compressor air-discharging; Promptly increase various oil separating devices near compressor crank shaft afterbody or loam cake outlet pipe vicinity; Though this type oil separating device can effectively reduce the compressor oil content, will cause compressor inner structure complicacy, cost of production to increase simultaneously.
[summary of the invention]
The present invention provides a kind of simple in structure, convenient processing and manufacture, improves noise elimination effect, the reduction compressor air-discharging noise of silencing apparatus, and can effectively reduce the oil content in the refrigeration agent, the exhaust silencer of raising compressor oil separating effect.
In order to realize the foregoing invention purpose, the technological scheme that the present invention adopts is:
A kind of exhaust silencer that improves the compressor oil separating effect; Comprise lid and be arranged on the mounting hole on the lid, be provided with the centrifugal flow guiding passage that the refrigerant pressurized gas that contain oil droplet is had the effect of centrifugal flow guiding viscous oil droplet in the silencing cavity of said lid internal face.
Said centrifugal flow guiding passage is axially stretching out and be a plurality of straight plate shape guide plate that setting is radially dispersed at the center with the center of circle of lid internal face from the lid internal face.
Said centrifugal flow guiding passage is axially stretching out and be setting is dispersed at the center along spirality a plurality of circular arc guide plates with the center of circle of lid internal face from the lid internal face.
Said guide plate is welded on the lid inwall.
The invention has the beneficial effects as follows:
The present invention is not increasing under the prerequisite of product cost basically; In the silencing cavity of exhaust silencer internal face, add a plurality of guide plates that lineal shape radially is provided with or the circular arc spiral is provided with; When pressurized gas when air-flow path flows through, the refrigerant that contains oil droplet with certain flow rate a plurality of guide plates form in the centrifugal flow guiding passages circuitous walk through, oil droplet sticks to the surface of guide plate under centrifugal action; Thereby reach the purpose that oil droplet is separated from gas mixture; Reach the oil that improves in the compressor block and separate effect, effectively reduce the oil content in the refrigeration agent, keep pump body structure fully lubricated; Simultaneously, integrated guide plate can strengthen the sound reflection effect on the baffler inwall, can further improve the noise elimination effect of silencing apparatus, reduces the compressor air-discharging noise.

[embodiment]
Embodiment one
As depicted in figs. 1 and 2; A kind of exhaust silencer that improves the compressor oil separating effect; Comprise lid 1 and be arranged on the mounting hole 2 on the lid 1; In the silencing cavity of lid 1 internal face, be provided with the centrifugal flow guiding passage 3 that the refrigerant pressurized gas that contain oil droplet is had the effect of centrifugal flow guiding viscous oil droplet; Said centrifugal flow guiding passage 3 is for from axially the stretching out and be a plurality of straight plate shape guide plate 4 that setting is radially dispersed at the center with the center of circle of lid 1 internal face of lid 1 internal face, and said straight plate shape guide plate 4 is welded on lid 1 inwall.
Embodiment two
As shown in Figure 3; Be with embodiment one difference; Said centrifugal flow guiding passage 3 is for from axially the stretching out and be that a plurality of circular arc guide plates 5 of setting are dispersed along spirality in the center with the center of circle of lid 1 internal face of lid 1 internal face, and said circular arc guide plate 5 is welded on lid 1 inwall.
As shown in Figure 4; The top of compressor is equipped with motor 6, at upper flange 8 upsides of the pump housing 7 of compressor the exhaust silencer 9 that the present invention uses is installed, through in the silencing cavity of exhaust silencer internal face, adding the guide plate that lineal shape radially is provided with or the circular arc spiral is provided with; The refrigerant that contains oil droplet with certain flow rate a plurality of guide plates form in the centrifugal flow guiding passages circuitous walk through; Oil droplet sticks to the surface of guide plate under centrifugal action, separate from gas mixture thereby reach oil droplet, reaches the oil that improves in the compressor block and separates effect; Effectively reduce the oil content in the refrigeration agent, keep pump body structure fully lubricated; Simultaneously, integrated guide plate can strengthen the sound reflection effect on the baffler inwall, can further improve the noise elimination effect of silencing apparatus, reduces the compressor air-discharging noise.
The above embodiment for preferred embodiment of the present invention, is not to limit practical range of the present invention with this just, and the equivalence that all shapes according to the present invention, structure and principle are done changes, and all should be covered by in protection scope of the present invention.
